TXW_DIRSEG4 SAP (Data file segment directory (replaced by txw_dirsg2: uuids)) Structure details
Description: Data file segment directory (replaced by txw_dirsg2: uuids)
Structure field list including key, data, relationships and ABAP select examples
TXW_DIRSEG4 is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Data file segment directory (replaced by txw_dirsg2: uuids)" Information within sap ABAP programs.
This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately.
i.e. DATA: wa_TXW_DIRSEG4 TYPE TXW_DIRSEG4.
The TXW_DIRSEG4 table consists of various fields, each holding specific information or linking keys about Data file segment directory (replaced by txw_dirsg2: uuids) data available in SAP. These include EXTRACT_ID (Data extract ID (to be replaced in release 99 by txw_uuid)), SEG_NUMBER (Segment number), SEGTYPE (Data file segment type), SEGDATA (Data file: Segment data code).. See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
